    Am I crazy, a compact triple?

    One of the things I suspected I would like about a road bike (and do) is the tight gearing. But, with the road bike in the shop, I'm back on a bike with a triple up front, and an 11-32 (8speed) cassette in the back. The two biggest improvements I can see that this bike needs is a lighter wheel set, and tighter cassette. It seems like the gears I want are never available on the chain ring I'm on now, I've lost the skill of shifting both front and rear for small gear changes, a compact double is easier. So, I'm starting to think about a 12-25 cassette, turning the bike into a compact triple, crazy or no?

    My trek 7200 came with an 11-34 mega range 8 speed cassette, 28/38/48 up front. I did put a 12-25 on it and did and do like it, I never used 38-34......38-25 is low enough for around here.

    If that makes it easier for you to get on the bike and ride, then it is not crazy. Everyone likes what they like.

    I have a compact double. I often wish I had a triple for the bigger hills. I'm only getting 70 rpm us a moderately steep grade. I like 90; need a Grannie gear for that.

    Compact traditionally referred to the crank, so I don't see how changing the cassette will make the drivetrain a compact one. My B road bike has had a 50x34 compact crank up front and a 11x34 cassette since I went to Italy a few years ago.

    My Salsa Casseroll came stock with a 26 - 36 - 48 triple chainring and 12 - 25 (9 speed) road cassette. I switched to 12 - 27 this year. Not crazy, but I do need to use the small chainring on climbs sometimes.

    IMO, the bike companies are trying with hybrids to be all things to all people. Granny gears and 11 - 32 or 11 - 34 cassettes for riders living in extremely mountainous areas or alternately, extremely unfit riders, middle gears to appeal to the average commuter or average fit rider living in mostly flat areas, and a big chainring for those riders looking to keep up with roadies. It makes perfect sense to change out the gearing to match your riding style.

    I'm running a 3x9 with bastardized deore mountain crank, 22/36/48 with a touring rear cassette 11-34. Front shifts a bit rough and bit slow on or off the 22... Using a high capacity deore XT rear derailleur.

    Riding on a trainer (trying to track the power curves on trainer road) does highlight why people like smaller gaps better gears on the cassette, but otherwise it doesn't seem to really matter if my speed is a little higher or lower at given cadence in selected gear. But then I don't ride in groups and have a wid-ish tolerance for cadences... Mostly because all cadences are not specifically too good...

    I moved from a 48-38-28 crank on my 7.3 FX to 42-32-22 when I was looking to move to a shorter crank for my knees. I love it. I am also considering going with a narrower range on my rear cluster when it comes time to replace it. With a 22 small ring in front, I don't think I need a 32 on the rear.

    I don't know what size rings your front derailleur will handle as small rings as I use, but if it is a mountain oriented crank/front derailleur, it should work for you. If it uses road fd and shifter you may have issues.

    ^^Yeah, this. Everything is up from here, some much more than others. I'm currently running a 26-39-48/11-34 9 speed cassette on my early 80's Trek, and happy to have it all. I'm not done yet figuring out the gearing, but it's gonna require a little more fitness and a ten-speed chain to end up where I wanna be.

    Awfully happy to spin up the 15-20% ers at 4.5 mph when I have to; anything's better than stopping.
